Question

How can I make this if statement work? I have three images that auto generate and if all 3 are the same I want message "You won!" to pop up.


@Override

public void actionPerformed(ActionEvent e) {

//PlaySound.play("C:/Users/wliu.GGC/Music/playSound.wav");
Random r = new Random();
ImageIcon picture1 = new ImageIcon("/Users/lalo/Desktop/pic/" + r.nextInt(3) + ".jpg");


ImageIcon picture2 = new ImageIcon("/Users/lalo/Desktop/pic/" + r.nextInt(3) + ".jpg");


ImageIcon picture3 = new ImageIcon("/Users/lalo/Desktop/pic/" + r.nextInt(3) + ".jpg");

label1.setIcon(picture1);

label2.setIcon(picture2);

label3.setIcon(picture3);

if (label1==label2 && label2==label3){
JOptionPane.showMessageDialog(null, "You won!"); }



}

Answer 1

i am not sure you can compare it like that because label1 equals picture1 not picture 2. what about having a condition to determine which picture the label gets? if (this) label2.setIcon(picture1)
else if (this)
label2.setIcon(picture2)
then perhaps you could compare in this way?

Answer 2

and if not, you could use variables in a pinch. if (this){
label2.setIcon(picture1); intLabel2=1;
}
then if (intLabel2==intLabel3 && intLabel2 == intLabel1)
"youwin!"
might not be the most accurate way to do it, but then again, I tend to just force code to work when i don't know the shortcut way!
